Nasal Strip With Non-Adhesive Central Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nasal strips provide only moderate torque for opening nasal passageways, cause discomfort upon removal, are difficult to place accurately, and can irritate the skin due to widespread adhesive use.
Innovation Solution
A nasal strip design featuring a non-adhesive central portion with a plastic covering over the adhesive surface, increasing torque, reducing skin irritation, and facilitating easier placement and removal by minimizing adhesive contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied across the entire nasal strip surface, then the nasal strip adheres strongly to the skin, but this causes discomfort upon removal and skin irritation
Solution Approach 1:
The nasal strip is divided into adhesive end sections and a non-adhesive central portion. The adhesive material is applied only to the end sections, segmenting the adhesive function from the central bridge area. This segmentation maintains reliable attachment at the ends while eliminating skin irritation in the central region.
Solution Approach 2:
Different portions of the nasal strip have different adhesive properties. The end sections possess adhesive quality for secure attachment, while the central portion has non-adhesive quality to prevent skin irritation. This local differentiation of quality optimizes both attachment reliability and comfort.
2Reliability
If adhesive is applied across the entire nasal strip surface, then the nasal strip adheres strongly to the skin, but this makes removal uncomfortable
Solution Approach 1:
The adhesive function is segmented to only the end sections, separating the strong attachment function from the removal comfort consideration. The central portion without adhesive provides a comfortable removal experience while the end sections maintain reliable attachment.
3Reliability
If the entire nasal strip surface is adhesive, then the nasal strip adheres well to the skin, but this makes it difficult to hold and place accurately
Solution Approach 1:
The non-adhesive central portion acts as a handling zone that is segmented from the adhesive end sections. This allows users to easily grasp and position the nasal strip during application without the complication of adhesive on the entire surface, while the end sections provide the necessary adhesive attachment.
4Reliability
If adhesive is applied across the entire nasal strip, then maximum skin contact is achieved, but this increases the area of skin that can be irritated
Solution Approach 1:
The adhesive coverage is segmented to exclude the central portion, reducing the total area of skin contact with adhesive. This segmentation maintains adequate attachment through the end sections while minimizing the area susceptible to irritation.
Solution Approach 2:
The nasal strip exhibits local quality variation with adhesive properties concentrated at the ends and non-adhesive properties in the center. This local differentiation reduces the overall adhesive-skin contact area, minimizing irritation while maintaining functional attachment.

AI summary
A nasal strip having a non-adhesive central portion situated between two adhesive end sections of the nasal strip. In one example, a thin plastic covering over the adhesive surface of the central portion of the nasal strip provides advantages of more torque obtained to open the nasal passageways, less discomfort on removal of the nasal strip, easier placement of the nasal strip onto the nose and less area of the skin on the nose that can be irritated by the adhesive interior surface of the nasal strip.
